MUSIC-LEAF TURNER.

Application filed August 13, 1927. Serial No. 212,716.

This invention relates to improvements in music leaf turners.

The principal object of this invention 1s to produce a mechanical device whereby the individual sheets or pages of music may be mechanically turned over in a manner s1milar to that now accomplished manually.

, Another object is to, produce a device of this character which maybe installed upon an ordinary piano or upon a music rack.

. A further object is to produce a device of this character which. is free of springs and like mechanical parts which are easily deranged.

' A still further object is to produce a device of this character which is neat in appearance and one which will not be ob ectionable to the eye.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings formmg a part of this specification and inwhich l ke numerals are employed to designate like parts throughout the same, i

Figure 1 is a front elevatlon of a music rack having my device applied thereto,

Figure 2 is a side elevation of the upper portion of my device,

Figure 3 is a cross section taken on the line 33 of Figure 4, and on an enlarged scale,

Figure 4 is a cross-section taken on the line 44 of Figure 3,

Figure 5 is a top plan view of the leaf engaging arms, I

Figure 6 is a cross section taken on the line 6-6 of Figure 5 showing the sheet engaging clips, and

igure 7 is an enlarged detail new showing a fragment of one of the'chps.

It has been common practlce for many years to turn the pages of music manually. This is oftentimes difficult to do without interrupting the playing, and I have therefore produced a device for mechanically accomplishing this object.

In the accompanying drawings wherem for the purpose ofillustratio n is showna preferred embodiment of my invention, the numeral 5 designates a box-like structure and the numeral 6 a backing secured thereto, against which the music book or composition is to be placed. The pages are designated by the numerals 7, 8, 9 and 11. A plurality of shafts 12, 13 and 14 are journaled within the box-like structure 5 and within suitable bearings 16 carried upon the back 6. These shafts are mounted in parallel relation as best shown in Figure 4:.

Mounted upon shafts 12. 13 and 14 are gears 17, 18, and 19 respectively. The gear 17 is provided with an opening 21 therein so as to permit the shafts 12 and 13 to pass therethrough while the gear 18 has an opening 22 to permit the shaft 14 to pass therethrough the purpose of which will be later 1 seen. Mounted upon the box-like structure 5 are keys 23, 24, 26, and 27,. 28, 29. The keys 23, 24 and 26 are secured uponrack bars 31,32 and 33 respectively, which rack bars each engage one of the gears 17 18 and 19. The keys 27, 28 and 29 are secured to 38 is secured to the keys and passes over a.

pulley 39 thence downwardly as shown at 41, and is connected to a pedal 42 placed conveniently for the operator to. place his foot thereon.

Upon the upper end of each of the shafts is secured an arm 43 and as they are identical but one will be described. Each arm carries a clip consisting of two plates 40 and 44'Wl1i0h have their lower extremities normally held in engagement with each other by a spring 46. The upper portion of these plates is provided with finger pieces 47 so that they may be easily pressed toward each other for the purpose of engaging the sheet of music. These finger pieces also provide means whereby arms may be manually moved if desired.

The operation of the device is as follows g A sheet of music is placed upon the boxlike structure after which each sheet is engaged by vone of the clips, after which the device is ready for operation.

Assuming that the buttons 27, 28 and 29 are all pressed in all of the sheets of music engaged by the clips will lie to the right of Figure 1. When it is desired to. turn the page, one of the buttons will be pushed as for instance the button 23 with the result that the rack bar 31 will he pushed inwardl, which will actupon the gear 17. This gear can rotate and due to the opening; 21 formed therein the gear will lllillic a half revolution before it engages the shafts 13 and 1%. This will throw the sheet from the right hand side of Figure 1 to the left, hand side. The same operation on buttons 2% and 26 will accomplish the turning of the next succeeding SliQGiS.

Should it he desired to return the gheet to their orieinal position the buttons and 29 ma 0e pressed with the result that the rack harr; 3%. 3t and 3? will function in the same manner with the exception that a reverse movement ot the gears l7, l8 and 19 will he a complished. Should it he desired to turn the pa by employing the feet. one of the peddes will he puehed, for instance the pedal connected to push button 23 the result being that a pull upon the cable 28 will be transmitted to the key. The remainder of the operation is identical to that- ;ahove described.

It will thus be seen that I have produced a very simple device which will accomplish all of the otuects herein set forth.

It is to he understood that the form of 1e inqterial size, shape and arrangei'nent of parts may he resorted to Without departing from the spirit of the invention or the PM)! e of the suhjoined claim.

ilYillg thuedeseribed my invention, I

112* V in a RHiHiC leaf turner a hon-like Structure, 1: hact-zing secured to said hex-like structure, a plurality o'l parallel spaced shafts eupported in said hoxdike strlu-ture. a gear secured to each of said shafts, certain of said gears having" senii-curular opening} therein. certain of said Shafts crtiei'idingrthrough said openin; a rack engaging each of said {t?!1i ,,-21 pueh hutton secured to each of said at a point outside oi said box-like structure, an arm secured to each of said uhatts at its upper extremity. and a clip secured to each of said arms for the purpeee specified.

In testimony whereof I am); my signature.
